Abstract (en)
[origin: WO2017124189A1] A method of determining locations of access points in a venue, one or more electronic devices configured to receive radio signals from the access points, the method comprises: generating and storing, at a server in communication with the one or more electronic devices, a database comprising information received from the one or more electronic devices, the information comprising: values associated with a radio signal characteristic of the radio signals at locations of RF scan capture by the one or more electronic devices and access point identifiers representing access points corresponding to the values, the locations of RF scan capture being unknown at a time of RF scan capture; assigning correlation values to quantify similarity between the values for pairs of the access point identifiers; mapping the correlation values to correlation ranges based on known locations of at least two of the access points; determining the locations of the access points based on the correlation ranges and the known locations.
